Tinycontrol 75A current sensor The current sensor is designed to measure the current flowing through the cable. The measurement is carried out using the Hall phenomenon, which means that there is no need to switch the meter into the measured circuit. Measurements are performed using sensors with galvanic isolation, which ensures safety and no problems with uncontrolled current flow through the measuring circuits. Analogue voltage proportional to the measured current is given at the sensor output. Power supply from 3 V to 5.5 V ensures compatibility with systems operating on these voltages.
